Here's a Fun Resource: Fact Monster

A new resource from Infoplease directed at kids, Fact Monster.com is interesting, easily navigable and full of information from the presidential elections to Project Runway. A preliminary search on "dolphin" (because Xavier was blathering about how he wants a pet dolphin instead of doing his science assignment) brought up not just definitions but links about the Miami Dolphins and literary allusions to dolphins in verse (from Byron's Childe Harold), so there is enough meat there for any kid to spend time hunting down tangential alleyways, plus trivia, games and quizzes and homework help.
